Decent size for a pump, easily fits in my pack.
The dual head seems to work pretty well for either valve type.
I have never successfully pumped a tire up to decent pressure with it.
High Volume / High pressure switch doesn't seem to make much difference.
I got so mad at this stupid pump that I finally got a CO2 inflator. Now I wonder why I ever even bothered with a pump.
The Genuine Innovations Air Chuck, with a cartridge, is 1/2 the price of this, and inflates a 2.3" MTB tire in seconds.
